我们从1977年开始萝卜一代杂种的育种工作,至1982年底已育成一代杂交种三个,并开始在生产上推广。现将工作情况报告于下。一、选育萝卜雄性不育系育成雄性不育系是培育萝卜一代杂种的关键。原始不育材料是1977年5月在清徐县城关公社西关大队“晋丰”萝卜采种田获得的,其出现率为0.8％。原始不育株属无花粉不育,其表现型是,花冠变小,花丝短缩,雄蕊退化,花药干瘦而空瘪,呈乳黄白色,不开裂,镜检花药内无花粉,但雌蕊正常(表1,图一见封二)。
Since 1977, we started the breeding of turnip hybrids. By the end of 1982, we have bred three generations of hybrids and started to promote the production. Now report on the work of the next. First, breeding radish male sterile lines Male sterile lines are the key to cultivate radish generation hybrids. The original sterile material was obtained in May 1977 by the “Guan Feng” radish plantation of the West Gate Brigade of Chengguan Commune in Qingxu County, with a prevalence rate of 0.8%. The original sterile plants are sterile pollen, its phenotype is smaller corolla, filament shortening, stamens degeneration, thin and empty anthers deflated, milky white, no cracking, no pollen microscopic examination, but normal pistil (Table 1, Figure I see Feng two).
